Note:The lifter bosses in SHP blocks are .220" taller than the bosses in early-style blocks that were not designed for hydraulic roller lifters. If you are installing aftermarket lifters with link bars in an SHP block, the lifters must be designed for use in 1987-up or Bow Tie blocks.
Due to the additional length of these aftermarket tie-bar lifters, they must be installed in the block before the cylinder heads are installed.
Why waste time sourcing, cleaning, machining, and prepping an old core in hopes it'll be usable when you could be guaranteed a new quality block without the expense of a full-race unit? Dart "SHP" Special High Performance Blocks enable you to affordably build a powerful and durable engine. Designed for high performance and heavy duty applications producing up to 600 horsepower, the SHP block is the ideal starting point for hot rodders, drag racers, circle track competitors, off-roaders and high performance marine enthusiasts. One of the great features of the Dart SHP block is its
provisions to use OEM hydraulic roller lifters.
There are mounting bosses in the valley for a factory stamped steel spider, and the lifter bores are machined flat on top to accommodate the "dog bone" alignment bars used on OEM hydraulic roller lifters. This allows an engine builder to take advantage of the fast acceleration and low maintenance of a hydraulic roller cam profile while using
inexpensive stock-type lifters.
